should give way to simplicity:
are used to clarify and make the speech more understandable; this
is reached with simple images (if they are complex and difficult
to interpret in stead of clarifying they confuse even more).
should use colour images: they allow you to make the most relevant
information stand out, emphasize the differences and make the image
look more attractive.
material should be this, a support to the speech, and should not be
the base of the presentation.
can not take importance away from the speaker.
are going to use support material, you need to practice with it in
rehearsals you need to recreate the same conditions which you are
going to have the day of the speech.
use of this support material requires a practice that you can only
achieve in a rehearsal.
the speaker has support material they feel more relaxed and neglect
rehearsing: don't let this happen to you.
to foresee that maybe when it comes down to the speech that the projector
might not work.
a difficult situation like this (however unlikely it may seem) the
speaker, besides preparing the speech with these support elements,
should also rehearse without the help of this material.

it can be seen from all angles.
explaining the image, the speaker should be standing next to the screen
so that the public can see and at the same time it is being explained,
wihtout having to look from one place to another (doing this the speaker
could loose his concentration).
the speaker is explaiming the image, he should be looking at the
public and not with his back to the audience contemplating the blackboard

use them with with large audiences (70-100 people).
the blackboard working with slides allows you to have the material
work as a support for the speaker, they eliminate one of the main
worries (they stop the speakers mind from going blank).
the slides you shoud try and make them simple, you need to get to
put down the main ideas (max 3/4 lines per slide), which the speaker
can then develop.
slides don't summarize the speech. You need to avoid making slides
with mixed ideas that don't really communicate anything and which
are difficult to follow.

which make the main ideas stick out.
not leave out any idea which appears on the slide, as the public will
be automatically drawn to it (if there is a point which is not important
it is best to leave it out).
project a graph you need to explain to the audience what it means,
how it can be interpreted (sometimes they are difficult to follow).
graphs you need to play with the scales in order to make the message
that you want to transmit stand out.
